Researchers in a Mayo Clinic-led study have shown how to detect a broad range of DNA mutations in noncancerous human tissues ...

Somatic mutations, the DNA changes that occur as our bodies grow and age, not only hold an important key to cancer but are ...

Single-nucleotide mutation maps and simulations indicate that mutation bias and GC-biased gene conversion largely shape nucleotide composition near human transcription start sites.

An international team of scientists has identified several genetic mutations that, should they arise, could potentially allow the avian influenza strain H7N9 to spread between humans. The findings are ...

A targeted lipidomic study in engineered human astrocytoma cells found that Alexander disease-associated GFAP mutations caused distinct, extensive changes in lipid composition, with R239C producing ...

In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

Clostridium botulinum bacteria produce a potent neurotoxin called botulinum toxin, which causes the serious illness botulism. The toxin attacks the nervous system, leaving the body unable to control ...

Scientists have mapped the genetics of cancer in cats for the first time at scale, uncovering major overlaps with human cancers. Key mutations—like those linked to breast cancer—appear in both species ...
